The fall armyworm (FAW), Spodoptera frugiperda, is a polyphagous pest native to the American continent that was first detected in Africa in 2016, where it has since become a major constraint to agricultural crops. The fall armyworm, Spodoptera frugiperda (J. E. Smith) (Lepidoptera: Noctuidae), poses a significant threat to maize production, capable of inflicting total yield loss. This lepidopteran pest's polyphagous nature and ability to infest crops from the seedling through the reproductive (cob formation) stages make its outbreaks particularly devastating. FAW has two genetic strains: the "rice strain" that prefers rice and other grasses, and the "maize strain" that feeds on maize and sorghum. Potential control strategies are often more suitable for farmers who lack the financial resources to purchase chemical pesticides or expensive pure seeds. Spodoptera frugiperda is extremely difficult to manage because of its capacity for fast reproduction, migration, and feeding on a variety of host plants. However, there are a number of pest management strategies that have been documented in other regions of the world that may be modified, verified, and applied in in many parts of East African countries. The excess application of chemical insecticides has negative impact on the ecosystem and human health, as well as the development of insect pest resistance, this had led to a search for cost-effective, low-risk, and target-specific alternatives. This review focuses on the efficacy of microbial pest management options, including entomopathogenic fungi, entomopathogenic nematodes, bacteria, and baculoviruses. Recommendations highlighted in this paper would undoubtedly pave the way for successful management of fall armyworm in maize and other related crops.
